1999 S80 T6 Rough idle then dying after pcv repair

[Mr Wolf]

It took awhile to get pictures up with work and such but I was finally able to, I think I have everything connected properly but a double check would be very much appreciated.

Also as an update, I was poking around to see if I had missed anything and found that the tube going from the round recessed thingy to the nipple on the right side of the intake manifold (please pardon my over technical description there) was very badly cracked and collapsed so I replaced it with some OEM vacuum line I had left over.

I also found that in moving the upper end of the PCV breather tube, the large metal one that connects above the engine, I accidentally crimped the fuel line going to the fuel rail, so I will need to replace that part now, I am thinking that it may not have been getting enough fuel after being started, but find it odd that it would start fine, stutter and not want to idle but if the gas pedal was pushed it would rev, not perfectly but would do it.

I am also having a good bit of difficulty finding the part to replace it, it is the fuel line from the fuel rail going down through the intake manifold, it crimped between the fuel rail connector and what looks to be a coupling from the rubber insulated fuel line to bare fuel line that travels around the engine.

Also I posted a picture of the to and from lines for the turbos, the two right hoses that have a good amount of oil coating them I would assume are coming from the turbos, would this be an indication of larger problems or just the PCV system and or normal for these cars.

Hi Mr. Wolf, as far as I can see, all the vacuum hoses are connected properly.

The 'round recessed thingy' is the blow off valve, if I'm not mistaken. The thin tube connects to the intake manifold, so when the pressure gets too high in the manifold, the BOV opens and releases compressed air (from the tube between the intercooler and the throttle module) into the air hose (after the air filter and mass airflow sensor). I think this is to avoid a pressure surge against the throttle.

The return tube from the PCV breather connects to the air tube that feeds the driver side/left hand side turbo, so when the PCV oil trap is full this tube will feed oil vapors into the turbo. Those tubes into/from the turbo looked similar in my T6 which I recently did the PCV job on.

[Mr Wolf]

thank you for letting me know all of the lines look correct, I couldn't imagine them going on in any other configuration but really wanted to be sure.

now I am just trying to find a way to get the replacement part for the fuel line section that I kinked, it is the part that connects to the fuel rail and goes through the intake manifold, I cant seem to find the part anywhere.
